But did not wish to implement a feature ahead of time. You can raise a JIRA issue . There are a few semantics issues to be ironed out as to which server to be hit and when and how shold a failiver happen. the loadbalancer approach may work but the slave must only talk to one master at any given point in time otherwise the replication will fail. > * > 2.

Master being choked as it's getting requests from 100 machines setup repeater nodes . setup a few slaves as masters also. and make some slaves replicate from these slaves instead of the primary master. > > Thoughts? > > Thanks, > Sameer. > -- > http://www.productification.com > -- --Noble Paul
